Problems solved by technology

However, the above three types of reinforced porcelain are all thick-bodied products, and all have different degrees of disadvantages: magnesia reinforced porcelain is difficult to form and fire, and the carcass is the thickest; high-alumina reinforced porcelain has a thick carcass and pores on the glaze surface. Many, general thermal stability; high silicon reinforced porcelain carcass is thick, glaze hardness is low

Abstract

The invention relates to a strengthen porcelain and a production process thereof, which more particularly relates to an eggshell strengthen porcelain and the corresponding production process. A body of the eggshell strengthen porcelain comprises kaolin, weathered potash feldspar, quartz, Alpha oxidized aluminum single crystal, zirconia single crystal, bentonite and talc. The production process of the eggshell strengthen porcelain comprises steps of ore sorting, batching, ball milling by adding water, sieving, removing iron, pressure filtering, clay preparation, forming, baking, biscuit firing, glazing, sintering to finish. The product of the invention has good whiteness, transmittance and thermo stability, high mechanical strength, smooth glaze, light instrument; the thickness of the product is approximately one half of the traditional strengthen porcelain only.
